May 2 (Reuters) - The killing of Osama bin Laden in a firefight with U.S. forces in a Pakistani town on Sunday caps a series of al Qaeda leaders captured or killed in the country since the Sept. 11 attacks.
Here are some of the other top militants hunted down in Pakistan, a country at the centre of the fight against Islamist militants.
* Khalid Sheikh Mohammed, the alleged operational mastermind of the Sept. 11 attacks, was captured in a 2003 raid on a house in the Pakistani garrison city of Rawalpindi, near the capital Islamabad.
* Ramzi bin al-Shibh, described as a key facilitator of the Sept.11 attacks, was arrested in September 2002.
* Abu Zubaydah, who is thought to have served as Bin Laden's field commander, was captured in Pakistan in March 2002.
* Libyan-born Abu Laith al Libi, a top al Qaeda operative in Afghanistan, was killed in a U.S. missile strike in Pakistan's North Waziristan in January 2008.
* Sheikh Said Masri, an Egyptian believed to have acted as the operational leader of al Qaeda, was killed in a U.S. drone strike in the Pakistani northwest in May 2010. Masri, also known as Mustafa Abu Yazid, was thought to have been the key conduit to Bin Laden and his No. 2, Ayman Zawahiri. (Writing by Sanjeev Miglani; Editing by Alex Richardson)
